Allerton TMD
Allerton TMD is a railway depot situated in Allerton, Liverpool. Situated opposite Liverpool South Parkway bus and rail interchange, it is visible from trains which are travelling between the former and and the overhead passageway above platforms 1 to 4 at Liverpool South Parkway. The depot is located less than from the Freightliner intermodal terminal at Garston Docks and is also from the Stobart Rail intermodal depot in Widnes. During the days of steam locomotive operation, the shed code was 8H between 1960 and 1963 and 8J between 1963 and 1973. Since 1973, when TOPS was introduced, Allerton's depot code has been AN. History During the British Rail era, Allerton depot was responsible for maintaining all of the main line and shunting locomotives which were operating in the Liverpool area, having an allocation of Class 08 diesel shunters and a wheel lathe. Users Merseyrail Until 2006, when a new wheel lathe was installed at Merseyrail's Kirkdale depot, Merseyrail's Cl ...

Liverpool
Liverpool is a city and metropolitan borough in Merseyside, England. With a population of in 2019, it is the 10th largest English district by population and its metropolitan area is the fifth largest in the United Kingdom, with a population of 2.24 million. On the eastern side of the Mersey Estuary, Liverpool historically lay within the ancient hundred of West Derby in the county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of the newly-created Lancashire County Council in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean li ...

Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gen ...

British Rail Class 156
The British Rail Class 156 ''Super Sprinter'' is a diesel multiple unit passenger train. A total of 114 sets were built between 1987 and 1989 for British Rail by Metro-Cammell's Washwood Heath works. They were built to replace elderly first-generation DMUs and locomotive-hauled passenger trains. Background By the beginning of the 1980s, British Rail (BR) operated a large fleet of first generation DMUs, which had been constructed in prior decades to various designs. While formulating its long-term strategy for this sector of its operations, British Rail planners recognised that there would be considerable costs incurred by undertaking refurbishment programmes necessary for the continued use of these ageing multiple units, particularly due to the necessity of handling and removing hazardous materials such as asbestos. In light of the high costs involved in retention, planners examined the prospects for the development and introduction of a new generation of DMUs to succeed t ...

Northern Rail (Serco-Abellio)
Northern Rail, branded as Northern, was an English train operating company owned by Serco-Abellio that operated the Northern Rail franchise from 2004 until 2016. It was the primary passenger train operator in Northern England, and operated the most stations of any train operating company in the United Kingdom. Northern Rail was replaced on 1 April 2016 by Arriva Rail North. History In 2000 the Strategic Rail Authority announced that it planned to reorganise the North West Regional Railways and Regional Railways North East franchises operated by First North Western and Arriva Trains Northern. A TransPennine Express franchise would be created for the long-distance regional services, with the remaining services to be operated by a new Northern Rail franchise. On 1 July 2004 the Strategic Rail Authority awarded the franchise to Serco-NedRailways, beating FirstGroup. The franchise was awarded for six years and nine months, with a two-year extension subject to performance targets ...

Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, Motor coach (rail), motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, Push-pull train, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

Goods Wagon
Goods wagons or freight wagons (North America: freight cars), also known as goods carriages, goods trucks, freight carriages or freight trucks, are unpowered railway vehicles that are used for the transportation of cargo. A variety of wagon types are in use to handle different types of goods, but all goods wagons in a regional network typically have standardized couplers and other fittings, such as hoses for air brakes, allowing different wagon types to be assembled into trains. For tracking and identification purposes, goods wagons are generally assigned a unique identifier, typically a UIC wagon number, or in North America, a company reporting mark plus a company specific serial number. Development At the beginning of the railway era, the vast majority of goods wagons were four- wheeled (two wheelset) vehicles of simple construction. These were almost exclusively small covered wagons, open wagons with side-boards, and flat wagons with or without stakes. Over the course of ...

British Rail Class 221
The British Rail Class 221 ''Super Voyager'' is a class of tilting diesel-electric multiple unit express passenger trains built in Bruges, Belgium, by Bombardier Transportation in 2001/02. The Class 221 are similar to the Class 220 ''Voyager'' units, but were built with a tilting mechanism enabling up to six degrees of tilt to allow higher speeds on curved tracks, most have five coaches, and they have a different bogie design. They have a maximum speed of . Currently these trains are divided between two operators, Avanti West Coast (20 sets) and CrossCountry (24 sets). The sets operated by CrossCountry had their tilt function disabled in 2008 to improve reliability and reduce maintenance costs. Details The Class 221s were produced as 5- or 4-coach sets. Each coach is equipped with a Cummins QSK19 diesel engine producing at 1,800 rpm, driving an electrical generator which powers two motors, each driving one (inner) axle per bogie via a cardan shaft and final drive. ca ...

British Rail Class 220
The British Rail Class 220 ''Voyager'' is a class of diesel-electric high-speed multiple unit passenger trains built in Belgium by Bombardier Transportation in 2000 and 2001. They were introduced in 2001 to replace the 20-year-old InterCity 125 and almost 40-year-old Class 47-hauled Mark 2 fleets operating on the Cross Country Route. They were initially operated by Virgin CrossCountry and since 2007 have been operated by CrossCountry. Technical details All coaches are equipped with a Cummins QSK19 diesel engine of at 1800 rpm. These power a generator which supplies current to motors driving two axles per coach, with one axle per bogie powered. Voyagers have both air and rheostatic brakes. They are fitted with Dellner couplers, like the Class 222 operated by East Midlands Railway and the Class 390 ''Pendolino'' electric trains used by Avanti West Coast, meaning they can be coupled in rescue/recovery mode (air brake only) in the event of a failure. 220s and 221s can also ...

Virgin CrossCountry
Virgin CrossCountry was a train operating company in the United Kingdom operating the InterCity CrossCountry passenger franchise from January 1997 until November 2007. Virgin CrossCountry operated some of the longest direct rail services in the United Kingdom but most avoided Greater London after 2003. All services called or terminated at Birmingham New Street. The company traded under the Virgin Trains brand, along with the InterCity West Coast franchise, however the two franchises were operated by separate legal entities. History Virgin Rail Group was awarded the InterCity CrossCountry franchise in November 1996, with operations commencing on 5 January 1997. Services were operated by a wholly owned subsidiary, CrossCountry Trains Limited. In October 1998, Virgin Group sold 49% of the shares in Virgin Rail Group to Stagecoach. In the wake of the collapse of Railtrack and the inability of Network Rail to deliver on the 140 mph West Coast Main Line upgrade, both the Vir ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

British Rail Class 508
The British Rail Class 508 (or 4PER) electric multiple unit (EMU) passenger trains were built by British Rail Engineering Limited, at Holgate Road carriage works, York, in 1979–80. They were the fourth variant of BR's standard 1972 design for suburban EMUs, eventually encompassing 755 vehicles and five classes ( 313/ 314/315/507/508). They have worked mostly on the Merseyrail network since 1983 and continue to do so, having been refurbished by Alstom's Eastleigh Works. The Class 508 unit is now years old. Description The class was developed for Merseyside, following extensive trials and testing of the 4Pep/2Pep stock that was built in the early 1970s. Testing of Class 313 took place on the Northern Line on Merseyside, using 313013/063 which were loaned from the Great Northern Line of the Eastern Region to Hall Road TMD. Original plans were drawn up for 58 Class 508s to be constructed, although costing issues limited the eventual number to 43. However, following planning ...
